Next patch fixes scrolling between droids and has option to turn off screen fritz effects, and has an indicator on your current droid at the bottom. Also, droid can be selected with keys 1...8.

Due out possibly later today.

Droid AI is not designed to keep them alive, it's designed to make them kill other droids. If you want droids that are better at staying alive get armoured ones, or ones with more hitpoints, and try to ensure they've got multicore brains. Their only other purpose is as a meat shield and emergency hosts when your current host gets the finger.
